D.J. Gongol and Associates, Inc. are the exclusive manufacturer's representatives for the Gorman-Rupp lines of municipal water and wastewater treatment systems in the states of Iowa and Nebraska. The Gorman-Rupp Company is the world's leading manufacturer of self-priming centrifugal pumps, and we are their proud representatives for municipal water and wastewater treatment applications in Iowa and Nebraska. Gorman-Rupp pumps are reliable and easy to maintain.

The Gorman-Rupp line of air-driven diaphragm pumps are ideal for moving sludges and slurries. The Gorman-Rupp Ramparts Division builds the best sludge and slurry pumps on the market, and D.J. Gongol & Associates, Inc. is proud to point to a long list of satisfied Ramparts air-driven diaphragm pump users in Iowa and Nebraska.

Solids-laden fluids like sludge and slurry are hard to move -- unless you're using a Ramparts air-driven diaphragm pump built by Gorman-Rupp. Ramparts pumps are unlike any others. Their rugged casings and dependable air-driven pistons keep them operating trouble-free for years on end. Here's how it works:

Intake stroke of a Ramparts air-driven diaphragm pump
Air is driven into the bottom of the air cylinder, raising the piston inside and lifting the diaphragm. As the diaphragm is raised, the check valve ball on the intake side is lifted and liquid flows into the pump. When the piston has risen to the top, the pump cavity is filled and the pump is ready for discharge.

Discharge strok of a Ramparts air-driven diaphragm pump
Compressed air is then forced into the top of the diaphragm chamber, pushing the diaphragm down and evacuating the pump cavity. The check-valve ball on the discharge side is lifted and the pump is ready for the next cycle.

Notice that the Gorman-Rupp Ramparts air-driven diaphragm pump has only three moving parts -- so there's almost nothing to maintain or wear out. Rebuild costs are a tiny fraction of the cost of a new pump, and every Ramparts sludge and slurry pump is built to last for years of trouble-free operation.
